Measure of Intracr Art Flow, Whole Blood mRNA, New Tech 7

This code describes a novel diagnostic procedure that measures the expression levels of specific messenger RNA (mRNA) biomarkers in whole blood to assess intracranial arterial blood flow. This technology offers a non-invasive approach to evaluate cerebral perfusion by analyzing genetic material indicative of vascular activity within the brain.

This code is used when physicians are utilizing this new technology to evaluate patients suspected of having compromised intracranial arterial flow, such as in cases of acute ischemic stroke, transient ischemic attack (TIA), or other cerebrovascular conditions. It would be applied when the intent is to gain insight into cerebral blood flow dynamics through molecular analysis rather than direct imaging.

• Ensure documentation clearly specifies the use of whole blood mRNA analysis for intracranial arterial flow assessment.
• This code is for a "New Technology Group 7," indicating it's a novel procedure; verify that the specific technology used aligns with this grouping.
• Do not use this code for direct imaging studies of intracranial arterial flow (e.g., CTA, MRA, transcranial Doppler).
